Here it is! It is called the Instigator Gas Tank and modeled after the vintage Wassel tanks. It holds about 2.2 gallons if you fancy the Frisco style (shown) or 2 gallons if you go for the deep tunnel. All tanks have a late style 74+ screw in gas cap bung, along with a female 3/8 NPT petcock bung. The tunnel has 1.75" of clearance. A good peanut gas tank as is or a good base to tweak it to make it your own. Price is only $199.99 plus shipping. Detroit Bros.
